Secondary Connector Rows C and D

The secondary connector rows C-D have the following subsystems:
6.2.1

PCI Express™

The conga-TR3 does not offer PCI Express lanes on the C-D connector. For more information on supported PCI Express lanes, see section 6.1.7.
6.2.2

PCI Express Graphics (PEG)

The conga-TR3 supports a x8 PEG interface. The default configuration of the PEG interface is 1 x8 link. The interface can be configured as a 2
x4 link via the setup menu.
6.2.3

Digital Display Interface

The conga-TR3 offers two dedicated Digital Display Interfaces (SoC DP1 and DP2) on the C-D connector by default. These interfaces support
dual-mode DisplayPort 1.2 only. To support HDMI/DVI, an external level shifter e.g PTN3360D should be implemented on the user's carrier
board.
The conga-TR3 can support a third DDI interface on the C-D connector but only as an assembly option (customized variant). The customized
variant with the optional DDI interface (third DDI interface) does not support LVDS/eDP interface.
The conga-TR3 supports up to three independent displays (a maximum of two independent HDMI/DVI displays only). Any combination of
DisplayPort, HDMI/DVI and LVDS is possible as shown in the table below:
